Star is a very fast, POSIX-compliant tar archiver, maintained for more than 30 years.
It saves many files together into a single tape or
disk archive, and can restore individual files
from the archive. It includes command line
interfaces for the "tar", "Sun-Tar", "cpio",
"pax", and "gnutar" command-line syntax. It
includes a FIFO for speed, a pattern matcher,
multi-volume support, the ability to archive
sparse files and ACLs, the ability to archive
extended file flags, automatic archive format
detection, automatic byte order recognition,
automatic archive compression/decompression,
remote archives, and special features that allow
star to be used for full and incremental backups.
It includes the only known platform independent
"rmt" server program.

The Big Faceless PDF Library is a Java class
library for creating PDF documents. The Extended
Edition offers the ability to create and edit
AcroForms, PDF's answer to the HTML form. Like
HTML forms, PDF forms can contain text boxes,
radio buttons, and can call JavaScript functions.
The Extended Edition also includes a PDF reader
for importing and editing, along with FDF support,
verification for digital signatures and text
extraction. Both variations offer full Unicode
support, encryption, embedded TrueType and Type1 fonts, barcodes, hyperlinks, and spot and calibrated
color.

Clam AntiVirus is an anti-virus toolkit designed especially for email
scanning on mail gateways. It provides a number of utilities, including
a flexible and scalable multi-threaded daemon, a commandline scanner,
and a tool for automatic database updates. The core of the package is an
anti-virus engine available as a shared library.

The STUBS Toolchain and Utility Build Suite is a
set of scripts which, together with a set of
pre-written configuration files, builds one or
more software packages in sequence. STUBS is
designed to work in very minimal environments,
including those without "make", and URLs are
included so source and patches can be downloaded
as necessary. Configuration files and scripts are
provided which create boot media for
Franki/Earlgrey Linux (one of several example
busybox- and uClibc-based Linux environments) and
the intention is that STUBS should be able to
rebuild such an environment from within itself.

smake is a highly portable 'make' program that makes commands up to date based on rules in Makefiles and on the timestamps of the related files. It implements a complete superset of the features of the classical POSIX/Unix make program. It warns about typical misuse of dynamic macros that prevent portability of makefiles. Its automake features allow you to run scripts to automatically create rules for unknown platforms.

For users on Linux and Unix, KDE offers a full suite of user workspace applications which allow interaction with these operating systems in a modern, graphical user interface. This includes Plasma Desktop, KDE's innovative and powerful desktop interface. Other workspace applications are included to aid with system configuration, running programs, or interacting with hardware devices. While the fully integrated KDE Workspaces are only available on Linux and Unix, some of these features are available on other platforms. In addition to the workspace, KDE produces a number of key applications such as the Konqueror Web browser, Dolphin file manager, and Kontact, the comprehensive personal information management suite. The list of applications includes many others, including those for education, multimedia, office productivity, networking, games, and much more. Most applications are available on all platforms supported by the KDE Development. KDE also brings to the forefront many innovations for application developers. An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner, eliminating the complexity and tediousness of creating highly functional applications.

Areca is a file backup system that supports data
compression (zip / zip64 format) and encryption,
incremental backups, FTP/SFTP file transfer, delta storage mode, and many other features. It
includes a transaction mechanism, which guarantees
the integrity of your backups. Two user interfaces
are available: a command-line interface (useful
for backup automation) and a graphical user
interface (useful for backup administration).

ADTPro transfers disks to and from Apple II and Apple /// computers and the modern world using any of these communications methods: serial/USB, UDP via the Uthernet or LANceGS Ethernet cards, or audio via the Apple's cassette ports. ADTPro has comprehensive bootstrapping support for otherwise diskless Apple IIs. The home page includes extensive tutorials for getting started.

Nyagua is a little piece of software that may help
you to manage your home aquarium. It can store
data about measurements in aquariums and produce
graphs from these. It can store data about
expenses and produce a report with yearly,
monthly, and daily costs. It reports the
compatibility between fishes and plants in its
database. It can import fishbase.org XML data, and
your own pictures can be added.

Password Manager Daemon serves clients data via a Unix domain socket or over a remote TLS connection. The data is stored in an (optionally) encrypted XML file, and the client must provide the key to modify it. It has the option to use gpg-agent for key management (including smartcards). It is multi-threaded, allowing more than one client to be connected at the same time. Key retrieval may be done via a key file or a pinentry program. A key cache is used, so a client won't need to enter a passphrase each time one is required. It is very configurable. Libpwmd is also available as a separate project and is a library making it easy for applications to use Pwmd.
